DETAILED DESCRIPTION OF THE EMBODIMENTS

[0047] The embodiments of the present disclosure will be clearly described below in combination with the accompanying drawings to enable the aforementioned objectives, features, and advantages of the present disclosure to be more obvious and understandable. Multiple specific details are described in the following description to facilitate the present disclosure to be completely understood. However, the present disclosure can be implemented using multiple other methods different from the description herein, and similar improvements can be obtained by a person of skill in the art without contradicting the contents of the present disclosure. Therefore, the present disclosure is not limited by the specific embodiments disclosed below.

[0048] It should be noted that when an element is referred to as being fixed to another element, it can be directly fixed to another element or be indirectly fixed to another element via one or more intermediate elements. When the element is referred to as being connected to another element, it can be directly connected to another element or be indirectly connected to another element via one or more intermediate elements. The terms used in the description herein, such as vertical, horizontal, left, and right, are merely used for illustrative purposes.

[0049] In the present disclosure, slightly larger means that a cross section of a box body 100 can cover a maximum cross section of springs 500, and an area of the cross section of the box body 100 is larger an area of the maximum cross section of the springs 500 by no more than 30%. When the area of the cross section of the box body 100 is larger than the area of the maximum cross section of the springs 500 by more than 30%, the springs 500 may bend or tilt away from a direction of a longitudinal axis of the box body 100 after entering into the box body 100, causing two of the springs 500 to become transversely jammed within the box body 100 and to be prevented from moving from a bottom surface 110 of the box body 100 to a top surface 130 of the box body 100 under an elastic force. Preferably, the area of the cross section of the box body 100 is larger than the area of the maximum cross section of the springs 500 by more than 10%.

[0050] In the present disclosure, up is used as a directional term to refer to a direction along the longitudinal axis of the box body 100 from the bottom surface 110 of the box body 100 to the top surface 130 of the box body 100, and down is used as a directional term to refer to the direction along the longitudinal axis of the box body 100 from the top surface 130 of the box body 100 to the bottom surface 110 of the box body 100.

Embodiment 1

[0051] Referring to FIGS. 1-5, a box body 100 of a packaging container unit for storing and unloading springs 500 of Embodiment 1 is an integrally formed plastic part. FIG. 1 is a perspective structural view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 1. As shown in FIG. 1, the box body 100 of the packaging container unit for storing and unloading the springs 500 is a prismatic shape (a quadrangular prism). A top surface 130 of the box body 100 is closed. A side surface 140 of a top end of the box body 100 comprises an opening 141 for unloading the springs 500, and the opening 141 for unloading the springs 500 is sleeved with an outlet cover 142.

[0052] FIG. 2 is a longitudinal-sectional view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 1, and FIG. 3 is a bottom view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 1. From FIGS. 1-5, it can be seen that inner walls of side surfaces 120 of a bottom end of the box body 100 are disposed with four one-way toggle pieces 200. Ends of the four one-way toggle pieces 200 adjacent to a bottom surface 110 of the box body 100 extend to form connecting walls 210. The connecting walls 210 are connected to the inner walls of the side surfaces 120 of the bottom end of the box body 100. In other available implementations, the connecting walls 210 can also be connected to outer walls of the side surfaces 120 of the bottom end of the box body 100. It can be seen from FIG. 2 that the four one-way toggle pieces 200 extend toward an inside of the box body 100 to form acute angles with the box body 100, and forward deformation of the four one-way toggle pieces 200 can occur in a direction toward the top surface 130 of the box body 100.

Embodiment 2

[0053] A packaging method for storing and unloading springs 500 and a process of storing and unloading the springs 500 provided in Embodiment 2 are described below using the packaging container unit for storing and unloading the springs 500 in Embodiment 1 as a container in conjunction with FIGS. 4-8.

[0054] FIGS. 4-6 show diagrammatic views of a process for placing the springs 500 into the container.

[0055] When the springs 500 need to be placed into the container, the springs 500 are inserted from the bottom surface 110 of the box body 100. After the springs 500 abut the four one-way toggle pieces 200, the four one-way toggle pieces 200 are squeezed by the springs 500 to generate forward deformation with the acute angles being reduced. Then, the springs 500 move away from the four one-way toggle pieces 200 to slide toward the top surface 130 of the box body 100.

[0056] The springs 500 are loaded in sequence in a single line from end to end. As a number of the springs 500 in the box body 100 gradually increases, the springs 500 begin to be compressed, and a lowermost spring 500 of the springs 500 in the box body 100 abuts the four one-way toggle pieces 200. As the four one-way toggle pieces 200 cannot be reversely deformed, the springs 500 cannot move away from the bottom surface 110 of the box body 100.

[0057] FIGS. 7 and 8 show diagrammatic views of a process for unloading the springs 500 from the container.

[0058] When the springs 500 need to be taken out, the outlet cover 142 is opened, and an uppermost spring 500 of the springs 500 in the box body 100 can be taken out from the opening 141 for unloading the springs 500. As the number of the springs 500 in the box body 100 decreases, an amount of compression of the springs 500 decreases gradually, lengths of the springs 500 increase, and a next uppermost spring 500 of the springs 500 is pushed to the opening 141 for unloading the springs 500 due to an elastic force of the springs 500. The aforementioned operation is repeated until all required springs of the springs 500 are taken out.

Embodiment 3

[0059] FIG. 9 shows a perspective structural view of a packaging container unit for storing and unloading springs 500. A box body 100 of the packaging container unit for storing and unloading the springs 500 is a cylindrical shape. A top surface 130 of the box body 100 is closed. A side surface 140 of a top end of the box body 100 comprises an opening 141 for unloading the springs 500, and an outlet cover 142 covers the opening 141 for unloading the springs 500. A bottom surface 110 of the box body 100 is disposed with four one-way toggle pieces 200 (not shown in FIG. 9, as shown in FIG. 10). Ends of the four one-way toggle pieces 200 adjacent to the bottom surface 110 of the box body 100 extend to form connecting walls 210, and the connecting wall 210 are connected together to form an annular structure to be sleeved on outer walls of side surfaces 120 of a bottom end of the box body 100.

[0060] FIG. 10 shows a longitudinal-sectional view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 3, and FIG. 11 shows a bottom view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 3. It can be seen from FIGS. 9-11 that the four one-way toggle pieces 200 extend toward an inner side of the box body 100 to form acute angles with the box body 100. In this embodiment, gaps between the four one-way toggle pieces 200 are equal, and pairwise ones of the four one-way toggle pieces 200 do not interfere with each other. With this arrangement, when the four one-way toggle pieces 200 are subjected to pressure, a stress on the four one-way toggle pieces 200 and the annular structure is relatively uniform, which helps to improve durability of the four one-way toggle pieces 200.

Embodiment 4

[0061] FIG. 12 shows a perspective structural view of a packaging container unit for storing and unloading springs 500. A box body 100 of the packaging container unit for storing and unloading the springs 500 is a prismatic shape (an octagonal prism). A top surface 130 of the box body 100 is closed. A side surface 140 of a top end of the box body 100 comprises an opening 141 for unloading the springs 500, and an outlet cover 142 covers the opening 141 for unloading the springs 500. The outlet cover 142 is directly formed on the box body 100 and is integrally molded with the box body 100.

[0062] FIG. 13 shows a longitudinal-sectional view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 4, and FIG. 14 shows a bottom view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 4. As shown in FIGS. 12-14, it can be seen that side surfaces 120 of a bottom end of the box body 100 are disposed with eight one-way toggle pieces 200. Ends of the eight one-way toggle pieces 200 adjacent to the bottom surface 110 of the box body 100 extend to form connecting walls 210, and the connecting walls 210 are adhered to inner walls of the side surfaces 120 of the bottom end of the box body 100. The eight one-way toggle pieces 200 extend toward an inner side of the box body 100 to form acute angles with the box body 100. In this embodiment, pairwise ones of the eight one-way toggle pieces 200 do not interfere with each other.

Embodiment 5

[0063] FIG. 15 shows an unfolded diagrammatic view of a packaging container unit for storing and unloading springs provided in Embodiment 5. As shown in FIGS. 15-18, the packaging container unit for storing and unloading the springs 500 is unfolded to define cardboard. In other available implementations, the packaging container unit for storing and unloading the springs 500 can be a plastic sheet. Two sides of the cardboard respectively comprise two adhesive surfaces. The packaging container unit for storing and unloading the springs 500 can be obtained by adhering the two adhesive surfaces to each other. A box body 100 of the packaging container unit for storing and unloading the springs 500 in Embodiment 5 is a prismatic shape (a quadrangular prism). A bottom surface 110 of the box body 100 comprises an opening (not shown in FIG. 15). Side surfaces 140 of a top end of the box body 100 extends to form two extendable surfaces 300 opposite to each other. Ends of the two extendable surfaces 300 away from the box body 100 comprise two connecting surfaces 311. The two connecting surfaces 311 can be connected to form a second top surface 310 through first insertion sheets 301 so as to define an opening 141 for unloading springs 500 on adjacent surfaces of the two connecting surfaces 311 (the second top surface 310 and the opening 141 for unloading the springs 500 are not shown in FIG. 15, as shown in FIG. 18). An upper side of the side surfaces 140 of the top end of the box body 100 adjacent to the two extendable surfaces 300 extends to form two first top surfaces 400 opposite to each other, and the two first top surfaces 400 are configured to be connected together through second insertion sheets 401.

[0064] Side surfaces 120 of a bottom end of the box body 100 are disposed with four one-way toggle pieces 200 (in FIG. 15, the four one-way toggle pieces 200 are in an unfolded state and have not extended toward an inner side of the box body 100 yet). Ends of the four one-way toggle pieces 200 adjacent to the bottom surface 110 of the box body 100 extend to form connecting walls 210 (not shown in the FIG. 15, as shown in FIG. 16). The connecting walls 210 comprise position-limiting buckles 211, and the side surfaces 120 of the bottom end of the box body 100 comprises buckling grooves 121 corresponding to the position-limiting buckles 211. The four one-way toggle pieces 200 are connected to the side surfaces 120 of the bottom end of the box body 100 through a cooperating connection of the position-limiting buckles 211 and the buckling grooves 121. Folding creases 600 are respectively disposed on the two extendable surfaces 300 and between the two extendable surfaces 300 and the side surfaces 140 of the top end of the box body 100, and the two extendable surfaces 300 are configured to be folded toward the inner side of the box body 100 through the folding creases 600.

[0065] FIG. 16 shows a longitudinal-sectional view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 5 when the two extendable surfaces 300 are in a folded state. FIG. 17 shows an enlarged view of part A in FIG. 16. At this time, the four one-way toggle pieces 200 extend toward the inner side of the box body 100 to form acute angles with the box body 100. The two extendable surfaces 300 are folded to be disposed in the box body 100, and the top surface 130 of the box body 100 is closed by the two first top surfaces 400.

[0066] FIG. 18 shows a longitudinal-sectional view of the packaging container unit for storing and unloading the springs 500 provided in Embodiment 5 when the two extendable surfaces 300 are in an unfolded state. As shown in FIG. 18, the two extendable surfaces 300 are unfolded to form the second top surface 310 so as to expose the opening 141 for unloading springs. At this time, the two first top surfaces 400 are in a separated state.

Embodiment 6

[0067] A packaging method for storing and unloading springs 500 and a process of storing and unloading the springs 500 provided in Embodiment 6 are described below using the packaging container unit for storing and unloading the springs 500 in Embodiment 5 as a container in conjunction with FIGS. 19-24.

[0068] FIGS. 19-20 show diagrammatic views of a process for placing the springs 500 into the container.

[0069] When the springs 500 need to be placed into the container, the two extendable surfaces 300 are folded toward the inner side of the box body 100 to close the top surface 130 of the box body 100. At this time, the top surface 130 of the box body 100 is in a closed state, so that the springs 500 cannot be separated from the box body 100 from the top surface 130 of the box body 100 after the springs 500 are disposed into the box body 100.

[0070] The springs 500 are inserted from the bottom surface 110 of the box body 100. After the springs 500 abut the four one-way toggle pieces 200, the four one-way toggle pieces 200 are squeezed by the springs 500 to generate forward deformation with the acute angles being reduced. Then, the springs 500 move away from the four one-way toggle pieces 200 to slide toward the top surface 130 of the box body 100.

[0071] The springs 500 are loaded in sequence in a single line from end to end. As a number of the springs 500 in the box body 100 gradually increases, the springs 500 begin to be compressed, and a lowermost spring 500 of the springs 500 in the box body 100 abuts the four one-way toggle pieces 200. As the four one-way toggle pieces 200 cannot be reversely deformed, the springs 500 cannot move away from the box body 100 through the bottom surface 110 of the box body 100.

[0072] FIGS. 21-23 show diagrammatic views of a process for unloading the springs 500 from the container.

[0073] When the springs 500 need to be taken out, the two first top surfaces 400 are separated from each other. After confirming that the two connecting surfaces 311 of the two extendable surfaces 300 are in a connected state, the two extendable surfaces 300 are unfolded. The two connecting surfaces 311 form the second top surface 310 to enable adjacent surfaces of the two extendable surfaces 300 define the opening 141 for unloading the springs 500. At the same time, as the two extendable surfaces 300 are unfolded, a total length of the packaging container unit for storing and unloading the springs 500 increases, and an amount of compression of the springs 500 decreases gradually. An uppermost spring 500 of the springs 500 is pushed to the opening 141 for unloading the springs 500 by an elastic force of the springs 500, allowing the uppermost spring 500 to be taken out from the opening 141 for unloading the springs 500.
